Hello everyone,
I would like to share some info about Huawei E3276 modem (full number E3276s-150). For all those who intend to use it with hAP be aware, it will NOT work for some reason (in my case only with hAP). I have 3 PCS but only one hAP so far. However, it gets recognized, adds ppp interface but it can’t connect by choosing any data port.
Best Regards!
Hi
I don´t know if there´s a significant difference between E3272 and E3372 ?, but I do have a E3372 working perfect connected to a hAP.
It’s running in Hilink mode ( no PPP interface )
Just for info if it may help

Running as LTE interface is already significant difference. E3276 and E3372 are completely different. Even E3372 non-hilink version. 
Ah !
I was under the impression that the E3276 and E3372 where quite similar… at least I learned something today
